Answer:
x = ± 2
Step-by-step explanation:
x² + 1 = 25 ( subtract 1 from both sides )
x² = 24 ( take square root of both sides )
x = ± 
= ± 
= 
× = ± 2
x = - 2 , x = 2

Answer:
<h3>5x</h3>
Step-by-step explanation:
The additive inverse of a function is that value added that will sum it up to zero
If y is the additive inverse of 4x, then y = -4x
Given the expression 17x+3y
Substitute y = -4x into the expression to have;
17x + 3(-4x)
17x -12x
5x
Hence the value of the expression in terms of x is 5x
